Malcolm Turnbull's new frontbench to be sworn in today

Prime Minister Malcolm Turnbull's new frontbench will be sworn in at Government House in Canberra today.

Unveiled by Mr Turnbull yesterday, Christopher Pyne and Greg Hunt were named as those taking on new roles.

All members of the previous cabinet have been reappointed, with some ministers shifted to new portfolios.

"My team will now get on with the job of governing, constructively working and engaging with the other parties in the parliament, to deliver the strong and secure future," Mr Turnbull said.

Mr Pyne has been appointed to the newly created role of Minister for Defence Industry, which will oversee the development of military technology and South Australia’s shipbuilding project.

Mr Hunt will move from Environment to Mr Pyne’s vacated Industry, Innovation and Science portfolio, while Josh Frydenberg will include the Environment role in his new title of Minister for Environment and Energy.
